Higgs Bosons and Electric Dipole Moments
Prof. Dr. William J. Marciano (Brookhaven National Laboratory, Dept. of Physics, Yale University, NY, USA)


In this talk, I will briefly review the recent discovery of a 125 GeV Higgs like particle at the LHC and comment on speculations regarding its properties.
One popular topic involves the two photon decay rate of the Higgs which shows early signs of being unexpectedly large.
Attempts to explain an enhanced rate allow for a new source of CP violation which can also lead to potentially observable electric dipole moments (edms) for atoms, nucleons and nuclei. If so, future searches for such moments at the 10^-29e-cm level could provide a unique window to phenomena that may help to explain the matter-antimatter asymmetry of our Universe. The basic physics of electric dipole moments and future experimental searches will also be described.
